SuiteSuccess Posted September 13, 2015 Report Share Posted September 13, 2015 Found me a trolley valve at truck salvage yard which I would like to install and tie into my Maxbrake to act as easily accessible slider control. Have looked at schematics on Resource Guide and Volvo e-media and am in over my head. Would anyone be willing to help walk me through the install at Hutch? 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

MrSeas Posted September 13, 2015 Report Share Posted September 13, 2015 Depending on you "parking brake valve" it may be more complicated than you might think. You will need some airline a "T" fitting or two or three and access to the backside of your instrument panel. Someone just did this on a "Gen 1" truck. Don't recall if they reported back how it turned out and what was involved. Does it also matter where you have plumbed the air for your brake controller?

rdickinson Posted September 13, 2015 Report Share Posted September 13, 2015 I just went thru this in Kamloops. On the Maxbrake unit I have there is a thin wire going thru the firewall to the engine compartment adjacent to the air manifold with the different colored hoses. My Maxbrake is mounted at the bottom of the console, left of the steering wheel assembly by my left knee. Hope you understand. The tech said in my case the wire was so small, like telephone wire, he was hesitant about splicing into it. That was the problem. He suggested I replace that one with a model that had 2 ports on the back. None of the HDT firms in this area are RV savy or really able to handle stuff like this. If you are able to get an answer, I'd sure like to hear it. Using the dashmount trailer valve would be a lot easier. Link to comment Share on other sites More sharing options...

Does it also matter where you have plumbed the air for your brake controller?My park brake manifold is a six port with a free "aux" port that my reading of the schematics may be the 3/8" supply to the trolley. The trolley itself has "supply, delivery, and exhaust ports". My MaxBrake transducer supply is from the 1/4" air supply that goes to the stoplight switch. My thinking is the trolley plumbed "normally" if applied would activate the Maxbrake just like the treadle brake. But I'm just not sure.BTW I just changed out my dash park brake manifold so I am able to get into the dash and behind the instrument display fairly easily. 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

It looks to me that as long as you plumb the Trailer Hand Valve Delivery line to the Tractor Protection valve, you would be plumbed for normal operation of the Trailer Hand Valve. The hard part will be in figuring where to plumb into the manifold.

A properly plumbed trolley valve applies pressure to the stop lamp switch when actuated, so yes, if you get the plumbing right, it's going to work as you expect.

SuiteSuccess Posted September 13, 2015 Author Report Share Posted September 13, 2015 Thanks everyone. Still hoping someone will volunteer to look at the schematics with me at Hutch to be sure I'm doing things correctly. I'll do all the manual labor. 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

bigstick Posted September 14, 2015 Report Share Posted September 14, 2015 I am confused. By trolley valve are you talking about the lever that actuates the trailer brakes? I have heard it called "johnson bar" and as I have always called it "the trailer spike". Johnson bar confuses me because we always called the lever that controls foreward and reverse on direct drive Cats the Johnson bar. Are there semi trailer trucks that dont have a trailer control valve? BTW. When I hooked up my maxbrake I plumbed the line into my trailer application gauge. Trailer brakes apply when I pull the "spike" Link to comment Share on other sites More sharing options...

Trailer brakes apply when I pull the "spike" That's what I'm calling the trolley. Have heard of it as trolley, Johnson Bar, trailer hand brake valve. I already have the Maxbrake installed and it works fine but, like Roger's, mine is mounted under the dash by my left knee. I really do not want it on top of the dash. The location it is in now would make it difficult to manipulate the slider bar if needed emergently. Thus if I had the trolley I could easily grab it and it would "act" like the slider. That was my intention. And in answer to you question, my truck did not come with a trailer brake hand control already installed. 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

Broncohauler Posted September 14, 2015 Report Share Posted September 14, 2015 The hand brake has been given a lot of names by truckers over the years. Johnson bar Broker handle Trolley handle or valve Can't say I ever heard it called a spike? But add it to the list. And like you when I hooked my max brake up it will also work on my broker handle.

sclord2002 Posted September 15, 2015 Report Share Posted September 15, 2015 Ronbo, I don't see any HDT networks supported on the DirecLink site I visited. Did you have to do anything special to get it to work properly on your truck ? I didn't think the vehicle computer knew anything about the air brakes unless the pressure was low , the brake switch actuated, or the traction control or ABS was doing its thing ??? Shows how little I know about the vehicles computers, I guess. Charlie Don't ever tell a soldier that he doesn't understand the cost of war.

Now I am slightly less ignorant about the DirecLink. Charlie Don't ever tell a soldier that he doesn't understand the cost of war. Link to comment Share on other sites More sharing options...

Ronbo Posted September 15, 2015 Report Share Posted September 15, 2015 They have a couple adapter cables. If it doesn't work on your rig they will give a full refund. I works great. The computer does have the brakes proportion info. Mine doesn't read the engine rpms so it will do to sleep after 5 min of the truck not moving. Brake application wakes it up. It doesn't affect operation as it doesn't go to sleep when the vehicle is rolling. It only does it when idling and not moving. As soon as I apply the brakes to place it in gear, the direct link wakes up. I don't even notice it.
